    Had to remove this from my dads Win XP run laptop. Malwarebytes remove all the fires but one. This file ended up being found at %UserProfile%\Application Data\hotfix.exe Was able to figure out this fir was the culprit due to the fact the creation date was the exact same as when the laptop first showed the problems and that the last accessed date and time were from when I last booted Windows normally. Since deleting the hotfix.exe while in safe mode the problem is fixed. Malwarebytes, Spyware Doctor and Spybot search and Destroy are all coming up clean where before they were flagging various other malware such as virtumonde

    Hope that what I found helps others who are having problems removing this malware program.

  2. Saul says:

    Had this same type of virus on my laptop yesterday and had a little trouble removing it. The virus i had did not want to let anything open like Internet Explore and other various software i had installed on my computer. I checked the virus with every possible virus removal software i had and did not show anything on it. I did a system restore to the laptop and did not want to restore successfully. So then i restarted the laptop and restored it in safe mode to an earlier time and it worked fine.

  3. Beth says:

    Microsoft Security Essentials popped up on my husband’s computer and said that it needed to reboot to complete a clean. I said OK and now it says that I need to put in the OS disks. It won’t let me do anything. I took the computer to Office Depot to get them to retrieve data and photos from the hard drive and they said the hard drive is empty.

    Is this possible? Do I have any other alternatives? I hate to have lost my only copies of photos of my son. I was stupid and didn’t have them backed up any where. Can anyone help?

  4. Josip says:

    Can you explain to me why I can not install MSE? It says that something’s missing. I wiped all other antivirus programs and tried everything but it will not. I have Win 7 Home Premium 64bit SP1. Thank you. I’m sorry if I write bad English, I’m from Croatia.
